You are correct on the files sent to Sony. The folders/files checked are dev_flash, app_home, Game.dat, patch.dat, and boot_history.dat. He isn't completely wrong when it comes to firmware tho, as some firmwares may have bugs with certain homebrew applications like PSNinja that keep them from clearing history as it should.
